Abstract: A multilayer printed wiring board prevents unnecessary emission of electromagnetic waves. The board includes at least two signal wiring layers, at least one ground layer, at least one power source layer, and a ground plane. The board further includes ground wiring adjacent to signal wiring in a signal wiring layer farther apart from said ground layer, the ground wiring being in the signal wiring layer. The ground wiring serves as a return current path for a signal current flowing in the signal wiring. In this structure, the return current path is reserved adjacent to the signal current path and the signal wiring is lower in impedance than the ground plane. The current can be fed back through a shorter closed loop. It is therefore possible to form a small loop to pass a signal current returning to a ground point and flowing through each signal wiring arranged in the board and a return current of the signal current. This minimizes unnecessary emission of electromagnetic waves.

Abstract: In a PBX network, a global database is provided in each PBX node for storing shared data for verification of authorized mobile stations when accessing the network via a wireless cell-site station. During a wireless mode, a mobile station monitors the strength of its downlink signal from a first cell-site station of a first PBX node. If it falls below a threshold, the mobile station begins a scan across the spectrum. If a strong signal is detected, it stops the scan and transmits a handover request message to a second cell-site station transmitting that strong signal. The second node receives the message via the second cell-site station to establish the mobile's verification. If the mobile station is an authorized user, the second node transmits a handover grant message to the second cell-site station, transmits a command message to the first node for a switchover to a link between the first and second nodes, and connects the link to the second cell-site station.
